摘要	Stress corrosion cracking (SCC) testing was conducted on pipeline steels to investigate the transition from nearneutral to high -pH environments via solution evaporation and concentration. The study clarified the roles of sulfate and bicarbonate in enhancing crack dissolution and their impacts on SCC. In sulfate -absent concentrated solutions, intergranular branching primarily resulted from direct propagation from the crack tip, accompanied by microcrack coalescence. The presence of sulfate effectively halted further growth by inducing crack -tip blunting, thereby reducing the mechanical driving force for crack propagation. This explanation clarifies why regions ideal for SCC exhibit no reported incidents, offering strategies for SCC mitigation.
